Enhanced Coal Workers Health Surveillance Program (ECWHSP)and provided additional details on 11 coal miners who exhibited rapid progression of coal workers’ pneumoconiosis (CWP) to severe disease. The third, Advanced Pneumoconiosis Among Working Underground Coal Miners â€“ Eastern Kentucky and Southwestern Virginia, 2006 (MMWR. July 6, 2007 / 56(26);652-655) provided a similar report of data for 975 participants from the ECWXSP but from a wider geographical area. This web page serves to provide the underlying data from these three reports. The files are provided in comma separated values (CSV) and SAS® format. In order to prevent identification of individuals, data for cells from <5 individuals have been excluded. For this reason, statistics calculated from these data, and the number of observations may be slightly different to those reported in the above publications.

CWP Statistics

NIOSH has an interactive query system for coal worker’s pneumoconiosis, the CWHSP Data Query System. Using this, individuals can obtain statistics on CWP occurrence by state, year, age, and tenure. Users should note, however that this system is currently being revised and that statistics generated in the future may not agree exactly with those from the current version. The differences arise from variations in the strategy used to deal with multiple radiographs from the same miner.

New data will be added annually, and due to the dynamic nature of data collection, which includes error correction and the addition of missing information, query system data are subject to change.
